Procedure

The mixture of 2.1 g of 2-nitro-5-dimethylaminobenzoic acid, 7 mL of cyclohexene and 1.5 g of Pd/C (10%) is heated under reflux conditions in 60 mL of ethanol for 6 hours. The hot reaction mixture is filtered through celite filter. The filtrate is evaporated to obtain 1.1 g of the title compound. M.p.: 232° C.
